Abstract

Provided are a terminal transmission power adjustment method, device, and terminal. The method comprises: obtaining the current distance between a human body and the terminal; obtaining the power adjustment value corresponding to the distance, according to the distance, from a pre-stored correspondence table of distances and transmission power adjustment values, the distance being the distance between the human body and the terminal; adjusting the terminal transmission power according to the power adjustment value. The terminal transmission power adjustment method of the present invention adjusts the antenna power outputted by the terminal in real time according to the distance between the human body and the terminal, such that the adjusted antenna transmission power of the terminal satisfies the required SAR value, that a user is not hurt by the antenna radiation, and that the terminal operation by the user is not affected.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a terminal transmission power adjustment method, device and terminal. Background technique [0002] As the mobile terminal plays an increasingly important role in life, the mobile terminal has become an indispensable tool in people's life and work, and people pay more and more attention to the security of the mobile terminal in daily use. In the process of using a mobile terminal, especially when people have conversations on the mobile terminal, people will be harmed by the electromagnetic radiation emitted by the antenna of the mobile terminal, and now more and more studies have shown that excessive electromagnetic radiation can cause people to Suffering from various diseases, even endangering human life, so various countries have put forward more and more stringent standards for the electromagnetic radiation of mobile terminal antennas, in order to reduce the damag...
